I saw this earlier in the week, and although I think there are some really strong moments, I didn't come out of the theater raving like some of the above posters.
Eric- I'm not old enough to have seen the original, but from the clips I've seen and what I gathered from Mandelbaum's A Chorus Line and the other Musical of Michael Bennett I believe Longbottom did make many nods to Bennet's staging. For example a spotlight goes to Effie's face during I Am Changing and then when it comes back out again she has changed costumes.
I didn't really like Sparks' new choreography. "Steppin' To the Bad Side" felt very anachronistic to me.
The cast is a VERY mixed bag. Moya Angela can really sing Effie, but as some others have noted her acting is a little weak, especially in the first act. In fact, up until "Heavy" everyone is pretty weak in the acting department except Chester and actor playing Marty. Maybe with time she'll settle more into the role.
Syesha Mercado is hit or miss as Deena. She has almost no lower register, and therefore the title song and the verses of "One Night Only" are almost inaudible. She didn't seem to have a character at all until the fight scenes with Effie at the end of act one. She didn't completely convince me that she was Magazine cover girl in act two either, but "Listen" came off well and kind of redeemed her.
Adrienne Warren was the best actress of three and she gave "Ain't No Party" and the subsequent scenes her all. Still, she had some trouble finding the humor in the dressing room where she talks about being a woman now.
I agree with the people saying Chester steals the show. He clearly has created the most layered character and is making definite acting choices for Jimmy. His dancing and singing is spot on, and (spoiler, I guess) his fall from fame/"The Rap" was affecting.
The actors playing Curtis and CC barely registered with me the whole evening.
At the end of the day this isn't a terrible revival, it just isn't that perfectly executed either.
Marie: Don't be in such a hurry about that pretty little chippy in Frisco.
Tony: Eh, she's a no chip!
